DI803 3BSE022362R1 | ABB | S800L 8-Channel Digital Input Module

Product Overview

The ABB DI803 (3BSE022362R1) serves as a robust 8-channel digital input interface within the S800L I/O family. Engineered for high-voltage sensing, it monitors 230 V a.c. or 220 V d.c. signals from field devices like limit switches or motor starters. This module features individually isolated channels, preventing cross-interference and protecting the wider Modulebus from voltage spikes. We supply this unit as 100% brand new original equipment to ensure maximum service life and compatibility with your ABB 800xA or Advant systems.

Technical Specifications

The DI803 provides high-impedance inputs to minimize power dissipation while ensuring clear signal detection across long cable runs.

Engineering Advantages

• Superior Channel Isolation: Each of the 8 channels maintains individual isolation. This architecture eliminates the risk of ground loops and prevents a single field fault from cascading through the entire I/O bank.

• Long-Distance Field Wiring: The module supports field cable lengths up to 600 meters for d.c. signals. This capability allows engineers to place I/O cabinets in centralized control rooms while maintaining reliable communication with remote field sensors.

• Configurable Noise Rejection: Selectable digital filters (up to 16 ms) suppress mechanical contact bounce and electrical noise. This ensures the controller receives clean, debounced signals even in environments with high electromagnetic interference.

• Optimized S800L Mechanics: The slim 86.1 mm width maximizes rail density. This compact form factor solves the challenge of upgrading legacy systems where cabinet space is at a premium.

FAQs

• Can I mix AC and DC signals on the same DI803 module?

  Yes. Because the DI803 features individually isolated channels, you can theoretically connect different signal types or phases to different channels without electrical interference, provided you observe the rated insulation voltage of 250V.

• Does the DI803 support Sequence of Events (SOE)?

  No, the DI803 is a standard digital input module. If your application requires 1ms time-stamping for event analysis, you should consider SOE-capable modules like the DI830.

• What is the significance of the 2000V dielectric test voltage?

  This high rating proves the module's ability to withstand significant transient surges. It protects your internal Modulebus and sensitive CPU hardware from external electrical strikes or heavy machinery switching noise.

• Is this a genuine ABB factory-sealed unit?

  Absolutely. We guarantee this DI803 3BSE022362R1 is 100% Brand New and arrives in original ABB packaging with intact security seals.
